Well I'm about to go ahead and get long tubes and a proper tune on my truck but I have read lately that the 3' orp may be to much for the 5.3. I'm pretty certain I'm gonna go with Pacesetter's but should I buy their y or have my muffler guy fab one? I'm going to be building a 6.0 eventually but in the mean time the 5.3 is going to have to work. Also what is a good cam for a crew cab nnbs daily driver? My truck and mods so far are. Thanks for the help!

just get the pacesetter y. dont try to over complicate things

 

get the 3" pacesetter y-pipe and have a muffler shop customize it so it can bend behind the crossmember thats how i did it on my crew cab worked great and sounds awesome.

 

Ok just wanted to get a opinion I didn't really want to do a hack job. How about a streetable cam for this heavy crew with a 5.3

 

212/218 low lift...

 

I think an Isky 210/216, .532''/.532'', 112* or 114* LSA would work well. That 210 lobe has a narrow 254* of duration @.006'' and is really torquy. For best results after you headers, and cam you should get a custom tune.

 

X2 Im having fun with mine.

 

^^yup runs real nice!! good cam to go with!
